The Mathematics Subject Classification (MSC) is a system used to
categorize items covered by Mathematical Reviews and Zentralblatt
für Mathematik. The current classification system has been used
since 1991 (a few minor changes and
additions were made in 1995). The MSC is broken down into over 5,000
two-, three-, and five-digit classfications, each corresponding to a
discipline of mathematics (e.g., 62 = Statistics; 62N = Engineering
statistics; 62N10 = Quality control). The 1991 Mathematics Subject
Classification is being completely revised. The new classification,
MSC2000, will be used starting in the year 2000.

You can browse the entire MSC but the earlier search of the MSC by text or classification code has been removed in this archive version.

The search program was based on one developed by Chris Eilbeck of Heriot-Watt University, Edinburgh.
